METAL SASH STRIP Filed NOV. 9, 1936 I INVENTOR. JZ/fl/J C. Neuenc/o/f MATTORNEY.

Patented Aug. 2, 1938 UNITED STATES PATENT OFFIQE 5 Claims.

This invention relates to metal sash strip and the object of theinvention is to provide a spring metal sash strip arranged to beinstalled in a sash to hold the glass panes in place therein andeliminate the use of putty.

Another object of the invention is to provide a 'metal sash strip havingan upright portion adapted to be secured in a groove in the sash andhaving a spring flange provided with av return bent portion extending atan angle to and yieldably engaging the glass pane to hold it in thesash.

Another object of the invention is to provide a metal sash strip havingseamed edges so as to give a smooth contact surface and provided with areturn bent angular flange adapted to form an angle between the glasspane and the edge of the sash.

A further object of the invention is to provide a metal sash strip whichmay be very readily secured in place and which when so secured pro-'vides a neat finish bevel between the glass and the edge of the sash.

A further object of the invention is to provide a spring metal sashstrip comprising an upright portion having an angular flange and saidflange being provided with a return bent spring metal portion extendingbeyond the upright portion and arranged to engage the glass pane.

These objects and the several novel features of the invention arehereinafter more fully described and claimed and the preferred form ofconstruction by which these objects are attained is shown in theaccompanying drawing in which Fig. 1 is a fragmentary view of a sashshowing my improved metal sash strips mounted therein.

Fig. 2 is a similar view showing one corner of a sash with the sashstrips mounted therein.

Fig. 3 is a section taken on line 33 of Fig. 1.

Fig. 4 is a section taken on line 44 of Fig. 2.

Fig. 5 is a perspective view of the spring metal sash strip itself.

The strip itselfis shown more particularly in Fig. 5 and comprises anupright or vertical portion I having an angular flange 2 extending at anacute angle to the upright portion l and having a return bent flange 3in contact with the flange 2 and extending at the same angle as theflange 2. The free edge of this return bent flange 3 extends beyond theupright portion to form an obtuse angle therewith and is provided withan inturned or seamed edge 4 which is turned under to provide a smoothcontact edge M for engaging the glass. Also, to prevent sharp edges, thelower edge of the upright portion I is provided with a return bentflange 5 forming a smooth seamed edge as shown and the upright portion Iis provided with nail holes 6 for attaching the metal sash strip in thesash.

As shown in Figs. 1, 2 and 4, the sash is provided with a shoulder 8 toreceive the glass pane El and this glass pane 9 engages against theshoulder 10 formed therefor in the sash. A groove H is formed in thesash 7 and extends downwardly from the shoulder 8 and is arranged toreceive the lower edge of the upright portion l of the metal sash strip.This is pressed down into the groove it until the return bent edge l2 ofthe sash strip engages the shoulder 8 while the seamed edge I l engagesthe face of the glass pane 9. While held in this position, nails I 5 aredriven through the sash and through the apertures 6 in the metal sashstrip to firmly secure it in place. When so secured, the seamed edge l4engages the glass pane 9 with a spring tension which will firmly holdthe glass pane 9 in position and the further the upright portion 1 ispushed down into the slot II the greater this spring tension will be.

The metal sash strip is preferably formed of spring bronze or othersuitable metal which has: inherent springiness so as to firmly engagethe glass and hold it in place. The return bent flange 3 of this stripmay be painted with the remainder of the sash and will provide a veryneat and even bevel between the sash and glass which will not have theirregularities usually produced with putty. Another advantage of mymetal sash strip is that it will overcome the difficulties had withputty cracking and falling out of the sash.

If desired, the seamed edge l4 may be coated with a cement, paint orrubber compound so that when the metal sash strip is secured in place, aseal will be formed between the edge I4 and the glass pane 9. If theglass pane 9 should become broken, the nails l5 may be pulled out toallow removal of the metal sash strips, at which time, a new pane 9 maybe inserted to position and the metal sash strips again secured in placein the sash by the nails l5. The sash strips may also be readily fittedtogether at the corners as shown in Figs. 1 and 2 and the completed sashwill present a much more finished appearance than a sash in which theglass is secured in place by putty.

In Figs. 1 and 3 I have also illustrated a metal sash stripfor a sashmullion. In this case, the sash mullion [6 does not provide sufficientmateiii rial into which grooves H may be out. For this construction, asash strip is provided comprising a U-shaped portion ll fitting over themullion 15 and secured in position by screws 18 and on each side of theU-shaped strip is a return bent flange H] which terminates in anangular'flange 20 extending at an angle into cdntact with the desiredthat as the screws [8 are turned up the flanges Zil are pressedoutwardly by the glass to the position shown in Fig. This produces aspring tension against the glass panes 9 which will firmly engage andhold the glass panes in position. e

From the foregoing description it becomes evident that the device isvery simple and'efiicient in operation, may be quickly and easilyinstalled in a sash, provides a neat finished appearance not obtainablewith putty, will not deteriorate with age and provides a device whichaccomplishes the objects described.

Having thus fully described my invention, its utility and mode ofoperation, what I claim and desire to secure by Letters Patent of theUnited States is 1. In a metal sash strip, the combination with a sashhaving a shoulder to receive a glass pane and provided with a groove inthe shoulder in front of the glass pane, a. sheet metal strip formed ofspring metal and having an upright portion fitting in said groove, aflange extending from one side of said upright portion and at an acuteangle thereto into engagement with said shoulder, said flange beingprovided with a portion return bent into engagement with the flange andproviding a free spring edge extending beyond the upright portion intoengagement with the glass pane and. means for securing the uprightportion in the groove.

2. In a metal sash strip, a sheet metal strip formed of spring metal andhaving; an upright portion provided with a return bent lower edge, theupper edge of the upright portion being provided with an out-turnedlongitudinal flange extending at an acute angle to the upright portion,the said flange; being provided. with a. portion return; bent intoengagement with the flange and prog/iding a free spring edge extendingbeyond the side of the upright portion op?- posite the flange andforming an obtuse angle therewith.

3. In a metal sash strip, aIsheet metal strip formed of spring metal andhaving an upright portion provided with a flange c n one side eXtendingat an acute angle to said upright portion, the said flange beingprovided with a return bent portion extending over the flange and incontact therewith, the return bent portion extending beyond the uprightportion and forming an obtuse angle with the side of the upright portionopposite the flange to provide a free spring edge.

4. In a metal sash strip, a sheet metal striphaving an upright portionprovided with a flange extending at an acute angle to said uprightportion, said flange terminating in a portion return bent intoengagement with the flange and providing a free spring edge extendingthereo-ver and beyond the upright portion, the extending edge of thereturn bent portion forming an obtuse angle with the side of the uprightportion opposite the flange.

5. In a metal sash strip, a sheet metal strip having an upright portionprovided with a flange extending at an acute angle to said uprightportion and having a portion return bent into ehgagement with the flangeand providing a free spring edge extending byond the upright portion onthe side opposite the flange.
